Application filed September 20, 1915. Serial No. 51,616.

To all whom it may concern: I

Be it known that I," EDWARD E. PINKER- TON, a citizenof the UnitedStates, and a resident of the city of Chicago, county of- Cook, andState of Illinois, have invented certain new and useful Improvements inFolding Boxes, of which the following is a specification. I v

My invention relates to improvements in foldable boxes and has for itsobject the provision of an improved construction of this character whichis exceptionally stiff and durable in use, and is provided with de--sirable surfaces for advertising purposes.

The invention consists in the combinations and arrangementsof partshereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawings forming a part of this specification, and in which Figure 1 isa perspective view of a box embodying my invention shown with the coverraised, Fig. 2, an enlarged longitudinal section taken on the plane22 ofFig. 1, shown with the cover closed, Fig. 3, a transverse section of thebox with the cover closed, Fig. 4, a plan view of one end of the boxwith the cover raised and the end partially unfolded, Fig. 5, a sectionthroughone end of the box showing the parts in slightly differentpositions, Fig. 6, a plan View of the blank from which the box isformed, Fig. 7, an enlarged section taken on the plane 77 of Fig. 1,shown with the cover closed, Fig. 8, a perspective viewof a modifiedform of construction, shown with the cover raised, Fig. 9, a plan viewof one end of the box illustrated in Fig. 8, shown with the cover raisedand the end partially unfolded, Fig. 10, an enlarged transverse sectionof the box illustrated in Fig. 8, shown withthe cover closed, Fig. 11',an enlarged longitudinal .section of the box shown in Fig. 8, showniwiththe cover closed, and Fig. 12, a plan View of the blank employed informing the box illustrated in Fig. 8.

The form of construction illustrated in- Figs. 1 to 7 inclusive, is madefrom a single blank cut and scored as indicated in Fig. 6'

to form a central bottom portion 13 having a side portion.14 at one edgeand connected therewith by means of the usual scored or creased line. Acover portion 15 is similarlyarranged at the outer edge of side portion14 and is provided with an edge flap 16 adapted to constitute one sideof the cover portion. Cover portion 15 is also provided with side-flaps17 and securing flaps 18 which are secured within the flap 16 tocomplete the cover, as indicated in Fig. 1, the side flaps 17 beingrovided with diagonal scores or creases 19 or folding flat. A sideportion 20 is arranged at the opposite sides of box portion 13 and isprovided at its outer edge with reinforcing portion or flap 21, saidparts being joined by scored or creased lines as indicated by the dottedlines. The

portion 21 is centrally split at 22 for substantially the full lengthofthe box and. is

laterally slit at 23 to form internal flaps which are themselves dividedby scoring into portions 2 1 and 25. A securing flap 26 is provided atthe outer edge. portion 21 as indicated, said securing flap 26 beingsecured to the inner side of the side 14 and end flaps 27 are providedat the ends of portion 21 serving to hold the parts thereof together.

and constituting in part the ends of the box. Likewise end flaps 28 areprovided at the ends of the bottom portion 13 and end flaps 29 and 30are provided on the ends of side portions 14 and 20. Tongues areprovided on the end flaps 28 and are divided by central scores orcreases into portions 31 and 32.

In-completing the box for sale the flap 26 is secured to the inner sideof side portion 14, as best shown inIFig. 3'and flaps 18 are secured tothe inner side of flap 16, as best shown in Fig. 1 when the box is readyfor sale, in which condition of the parts the portion 21 may be foldedflat upon the portion 13 and adjoining parts and cover 15 also foldedflat, as will be readily understood.

In arranging the box for use, the portion 21 is raised from contact withthe portion 13 and flap portions 2425 folded as indicated in Fig. 3, toconstitute hollow rectangular reinforcing side walls for the box. Thenend flaps 27 29 and 30 are arranged across corresponding ends of the boxand end flaps 28 folded up over the outer sides of the sameand thetongues 3132 folded downwardly between the side walls of the box againstwhich they frictionally engage to .hold the parts securely locked inposition.

isfactory. By this arrangement a very rigid, durable and attractive boxis formed, and one which presents considerable thickness of the side andend walls and particu larly of the side walls so that attractiveadvertising or printed directions may be placed on the tops thereof.

The modified form of construction illus trated in Figs. 8 to 12inclusive, is the same as that already shown and described except for aslight difference in the reinforcing portion 21. In this instance theportion 21 is not centrally split as before but the ends thereof areslit at 33 to form separated flaps 27, as shown in Fig. 12, otherwisethe two constructions are identical. This box is arranged for sale inthe same manner as the other one with the portion 21 resting fiat uponthe portion 13. When it is desired to arrange the box for use theportion 21 is raised and the portions 24 depressed to form the innersides of hollow side walls, the central portion 34 being connectedtherewith by means of scores or creases 35 to permit of the centralportion 34 being arranged fiat upon the bottom of the box, as shown.Then the end flaps are arranged to form the ends of the boxsubstantially as in the first described construction.

While I have illustrated and described the preferred forms ofconstruction for carrying my invention into effect, these are capable ofvariation and modification without departing from the spirit of theinvention. I, therefore, do not wish to be limited to the precisedetails of construction set forth, but desire to avail myself of suchvariations and modifications as come within the scope of the appendedclaims.

Having described my invention what I claim as new and desire'to secureby Letters Patent is:

1. A folding box formed from a single blank having a central bottomportion; a-

side portion at one edge of said bottom portion; a cover portion at theouter edge of said side portion; a side portion at the opposite edge ofsaid bottom portion; a portion at the outer edge of said last mentionedside portion foldable to form hollow sides inserted within saidbeforementioned sides; box end members on said bottom, cover and hollowside forming portions; and tongues on the bottom end members foldableinto the box and frictionally engaging the sides thereof, substantiallyas described.

'2. A folding box formed from a single blank having a central bottomportion; a side portion at one edge of said bottom portion; a coverportion at the outer edge of said side portion; a side portion at theopposite edge of said bottom portion; a por tion at the outer edge ofsaid last mentioned side portion foldable to form hollow sides insertedwithin said before-mentioned sides; box end members on said bottom,cover and hollow side forming portions; and tongues on the bottom endmembers foldable over said box end members into the box and frictionallyengaging the sides thereof, substantially as described.

3. A folding box formed from a single blank having a central bottomportion; a side portion at one edge of said bottom portion; a coverportion at the outer edge of said side portion; a side portion at theopposite edge of said bottom portion; a portion at the outer edge ofsaid last mentioned side portion foldableto constitute a false bottomand hollow side portions inserted in the box; and box end members onsaid bottom, cover and hollow side forming portions, substantially asdescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

EDWARD E. PINKERTON.
